Scan hard drive ∞
As I dropped my hard drive earlier, I spent a bunch of time checking it for damage.
Check for hardware issues ∞
.. by playing a video game. Honest.
Enigmata: Stellar War could reproduce a hang.
I suspected some power and possibly heat issues. Perhaps my video card or other parts weren't getting enough power. Perhaps my earlier electrical issues damaged my power supply in strange ways. I could also have some heat issues still, as I may not have applied thermal paste to my CPU as well as I could have, and its quality is poor.
I replaced my case and power supply. I have better air flow and fans, and have better power in the system.
I played Enigmata: Stellar War until I was satisfied things are ok again. Although things seem ok, Bloons seems to occasionally go very slow. Maybe that was just a connection issue between me and the game server, or the other player.
If my hang issues are gone, then my motherboard, video card and cpu are probably ok. I don't have to spend hundreds of dollars on parts now. Yay. Although I had done a bunch of research and found some good deals. Boo. At least I have a nice new case and power supply now.
